Direct air capture (DAC) offers a pathway for negative carbon emissions but remains constrained by a high desorption energy demand and uncertain long-term global CO₂ storage. Here, the authors present for the first time a robust and sustainable DAC alternative using a tailored decarbonizing hybrid anion exchanger or D-HAIX.
